Transmission of torque from motor to output without gearing
A direct-drive mechanism is a mechanism design where the force or torque from a prime mover is transmitted directly to the effector device (such as the drive wheels of a vehicle ) without involving any intermediate couplings such as a gear train or a belt .[ 1] [ 2] [ 3] [ 4]
